This video is part of a series of experiments I’ve done and is detailed on my site:

This video shows my new HV MOT Power Supply and with it some experiments using a magnetic field to blow out the arc.
I show the effect with and without a magnetic field on standard HV AC discharges and a half-wave doubler discharge.
The half-wave circuit is kind of non-ideal because it’s sort of self extinguishing since the current is intermittent. The idea for using this would be to interrupt a constant DC current, but it shows the concept of the magnetic quench. And the principals here can easily be extended for DC or other waveforms.
